显示结果

cfgrib.dataset.DatasetBuildError: key present and new value is different: key='pressureFromGroundLayer' value=Variable(dimensions=(), data=3000.0) new_value=Variable(dimensions=('pressureFromGroundLayer',), data=array([18000., 25500.]))

skipping variable: paramId==228001 shortName='cin'
cfgrib.dataset.DatasetBuildError: key present and new value is different: key='pressureFromGroundLayer' value=Variable(dimensions=(), data=3000.0) new_value=Variable(dimensions=(), data=25500.0)

这啥意思啊，彻底懵了

好像好了，这就是cape180_0mb的值吧？

这里面哪个是CAPE的值呢

而且为什么结果显示不全额 (12/29){:eb513:}{:eb513:}
